asterisk users - Jul 2015 - how to return a transfered call to the transferrer?

Hi all

Any of you guys could point me in the right direction?

I need to make that a blind transfer to return to the transferrer when the
transferee does not answer.

Scenario:
	. Miss Jane Doe, our front desk attendant, picks up an external call to
	Mr. Smith;
	. Miss Doe flashes, dial Mr. Smith's extension and then hangup;
	. Mr Smith's phone rings until timeout;
	. At this point, how to return the call to the Miss Doe's extension;

Cheers

Ethy

Do a channel dump on the transferred channel, you'll see marker channel
variables showing it's a transfer and that contain the sending peer name.
You can use dialplan logic to check if it's a transfer. If it is, you can
send the call back to the referrer peer.

I'm sorry. I couldn't find "channel dump" (Asterisk 11).

The closer I got was "sip show channel XXX".
And it does not return any clue about a transferred channel. 
At least none I could rely on.

Isn't there any dialplan variable? Other tip?

Cheers
